I just opened an account w/ interactive brokers, so I can have their realtime data feed, which I use to power Ensign charts ($40/month). IB will charge $10/month if $30 in commissions are not generated, so it seems like max cost for Ensign is $50/month, which is great because Ensign charts have pretty much everything that esignal or cqg has, I have no experience with quotetracker, but people seem to like it from what I have read on these boards. By the way, I also exclusively day trade 10yr futures, and use ensign to look at this market...
